To all w hom it may concern I Be it known that I, SIGMUND Fianna citizenof the United States, and a resident of Los Angeles, in the-county of'Los Angeles.

and State of Californiahave invented certain new and useful Improvementsin- Discharge Spouts for Liquid Containers, of which the following is aspecification.

This invention relates :to spouts of the character employed oncontainers forliquid and it is. especially serviceable for vesselsdischarge spout that can be neatly -telescoped within the container,when not in use.

Another object is to provide a spout having a valve that is opened bypressing the container toward the vessel being supplied with liquid fromthe container.

. Another object is to provide a'spout having-a valve which is opened bypulling the container away from the vessel being supplied with liquidfrom the container.

The accompanyingdrawings illustrate several forms of the invention:

Figure 1 is a side elevation of a'c'anteen with which'one form of theinventionis associated, a portion of the canteen being broken'away. toshow the spout telescoped within in'closed position.

Figure 2 is an enlarged longitudinal section of the spout shown inFigure 1, a fragment of the canteen also being shown. and

said-canteen being'turned on its side so. as r to bring the spout intohorizontal position.

The. spout isshown drawn out ready for use,'the valves being closed.

Figure 3 is a sectional-view similar to Figure 2, a portion of the:discharge tube -be ing broken away. Thefldischarge tube-is shown pulledoutwardly to ,open one of the V3lVeS.

and a fragment of the liquid container also being shown.

Figure 10 is an inverted pla'n view of the \T The embodiments ofthe-invention shown tip of the spout in Figure 7 in Figures 1 to 8,inclusive, are alike'in most respects, and the elements identical inboth embodiments will first be described. A liquid container isindicatedat 10 and is shown in Figure- 1 in the form of a canteen provided with ahandle 11 and with a cy-- lindrical neck 12 surrounding an opening 13formed in the top of the canteen. A detachable cap 1& normally closesthe neck 12, being, in this instance, screw-threaded upon said neck, asclearly shownin Figure" 1.

ed as indicatedat15 toreceive ascrewthreaded annular fiange-16 of abushing 17.

The Wall of the opening'13 is screw-thread- Theibushing '17' is providedwith internal screw threads 18 in itsinner end. Adapted "to be engagedand disengaged with said screw threads 18 is the screw-threaded end 19of a tubular valve or sleeve 20. Slidable through the bushing'lZ is adischarge tube 21, in the embodimentjofthe invention shownin Figure 2 ora discharge tube 22 in the embodiment of the invention shown in FigureThe tube 21 or 22*is provided. with a port or ports 23 which arenormally closed by-the sleeve 20 whether-the tube is drawn into theextended position for use shownin Figure 2 or is telescoped within thecanteen as in Figure -l.

Connectedto the sleeve 20 and forming an inward extension thereof is avalve cage 24 provided with longitudinal slots'or ways} 25 for theouterends'of a pin 26*which extends transversely through the tube 21 or22,. as the case may be. Loosely connectedto the pin 26 is alongitudinally ext nd ng stem 27 on which is slidably mounted a springseat 28 and a valve plug 29 Within the cage 24. Interposed between thespring seat 28 and valve plug 29 is a coil spring 30 which normallytends to hold the valve 29 against the inner open end 31 of the tube 21or 22, as the case may be. This spring 30 also normally tends to holdthe spring' seat 28 against abutments 32 formed at the inner end of thevalve cage 24. The stem 27 is provided with a shoulder 33 at its freeend adapted to be engaged by the spring seat 28 so as to prevent saidspring seat slipping off of the end of the stem 27 when the valve cageis pulled to the right as in Figure 3. The valve cage 24 is providedwith an internal shoulder or shoulders 34 which are flush with the innerend of the discharge tube when the cage is in the position shown inFigure 2 with both valves closing the discharge tube. The shoulders 34function to move the valve 29 away from the open tube end 31 to the.position shown in Figure 3, against the expansive force'of the spring30, when the tube 21 is pulled out to the position shown in Figure 3,thus opening the valve 29 soas to permit the passage of liquid from thecontainer into the open end 31 of the discharge tube.

The tube 21 is provided at its outer end with a bent tip 35 extendingsubstantially at a right angle to the other portion of the tube, and toinsure against collapse of said tip, when pressure is brought to bearagainst the tip to open the valve, there is inserted in said tip anangular member 36 which may be secured in place by any suitable means,for example, by a transversely extending rivet 37.

The discharge tube 22 is provided near its outer end with a dischargeorifice 38 and asolid tip or cap 39 prevents discharge of liquid at theend of the nozzle. The tip 39 is provided with a forked portion 40adapted to engage over the rim of a filling neck, such as that indicatedat A in Figure 7. The fork 40, when thus engaged with the filling neck,holds the tube 22 against endwise movement when the container, withwhich the spout is associated, is pushed toward or from the filling neckA. The outermost branch ofthe fork 40 is preferably V-shaped in crosssection so as to prevent slipping of the fork around the neck when thecontainer is pulled away from said neck.

In'the form of the invention illustrated in Figure 7, the bushing 17 isprovided in its outer end withhinternal screw threads 41' adapted toreceive the screw-threaded plug 42 formed bythe cap 39. lVhen the plug42 is screwed into the threaded portion 41, the inner end of said plugseats against a packing washer 43 so as to absolutely prevent theleaking of liquid between the positions shown in Figure 1, with the tube21 telescoped within the canteen and the cap 14 in place on the neck 12,said cap 14 will be unscrewed and removed from the neck;

Then the tip of the tube 21 will be grasped by the operator and pulledout until the resistance of the spring 30 is encountered.

Such resistance assures the operator that the spout is in extendedposition with the sleeve 20 against the bushing 17. The tubewill then beturned to connect the sleeve and bushing.

The tip 35 is then inserted. in the filling; neck of the vessel intowhich it is desired to discharge liquid from the container, .and--' theoperator will either move the canteen 10 toward or from such filling:neck, the tip 35 holding the spoutagainst endwise' movement while thecanteen is thus moved; H the operator pulls the canteen away from thefilling neck, the valve 29 will be caused to leave the open end 31 ofthe tube 21 so as to permit liquid to fiowfromthe canteen 100 into thespout and discharge from said spout. This open position of the tube'isshown in Figure 3 of the drawings. If the operator pushes the'canteentoward the fill-- ing neck, the tube holds the valve 29 while" thesleeve 19 moves toward the tip of the tube against the pressure of thespring '30,

and the ports 23 will thus be moved into open position beyond the innerend of the valve 20 so that liquid can flow from the canteen through theports 23 into the tube,

The positions 01" the parts justdescribed, to open the ports 23, areclearly shown in Figure 7 of the drawings, and it will be readilyunderstood that the embodiment of the in vention shown in Figure 7operates the same as that shown in Figures 1 to 6, excepting that theengagement ofthe tip 39 ofthe tube-* 22 withthe filling -neck A is alittle diflerent,

In Figure 7, the dischargeorifice 38fis above the level of the top ofthe filling neck'A, thus enabling the operator to see the liquiddischarge from the spout. The fork 40 will embrace the rim of thefilling neck Aso as to hold the spout 22- agafinst endwise move mentwhen the operator pushes the container toward or fromthefillihg'neck A;

Now referring to Figure 9 of the drawings, showing a valveless formOfthflyillvention, the liquid container' is indicated at 44 and isprovided with an opening 45 to receive abushing 46. The bushing 46-maybe secured in the opening-by solder-or'any other fastening means, andthe innerend of the bushing 46' is-pr Vided with internalf useas'shown'in the drawingl- The screwthreads" '47, 48 constitute one; form"of c0' operating means having a positive -'engag'e- Y1 ment forreleasably' holding "the tube 49.

Surrounding the opening 45'1is a" screw-" threaded neck "50 on thecontainer 4'4 adapted to receiv'ea'cap, not shown,lsimilar to the cap 14shown in Figurel of the/drawings, said cap being adapted to normallyclose the neck 50 when the spout 49 is shoved int-o the container. Thetip of. the noz zle i49'is' provided with a shoulder 51 which enablesone to more readily draw the: tube 49 into open position. The shoulder51, when the tube is pushed into closed position, engages the outer endof a coil spring 52 which surrounds the tube 49 and which is secured atits inner end to the outer end of the bushing 46. The spring 52 iscompressed by pushing the tube 49 inwardly until its outer end iswithinthe neck 50, and the function of the spring is to push the tip ofthe tube 49 out of the neck 50 when the cap, not shown, is removed fromthe neck 50, thus enabling the operator to the more easily grasp thetube to extend it into position for use.

In the form of the invention shown in Figure 9, the tub-e 49 will bedrawn out suflicient-ly far to engage the head 48 with the inner end ofthe bushing 46, and the tube will then be rotated to engage the screwthreads of the head and bushingso as to hold the tube in open position.When the operator has finished discharging liquid from the container, hewill turn the tube 49 to release the head 49 from the bushing and hewill then push the tube inwardly and apply the cap, not shown, to theneck 50 so as to prevent the discharge of liquid from and the entranceof dust to the container. WVhen the cap is in place, the container maybe placed in any position without the contents discharging therefrom. 1

It is to be understood that any other 00- operating releasibleconnecting means than screw-threads for holding the-discharge tubeextended may be provided between the bushing 17 and sleeve 20 and alsobetween the bushing 46 and the head 48.
